Objects and advantages of the invention will be set forth in part hereinafter andin part will be Obvious herefrom,'or maybe learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combinationspointed out in the appended claims.

The invention consists in the novel parts, construction, arrangements, combinations and'improvernents herein shown and described.

' The accompanying drawings, referred to herein and constituting a part hereof, illustrate one embodiment of the invention," and together with the descriptionQserve to explain the principles of the invention.

The present invention has for its object .the provision of a new and'ihiproved power-driven curl-winding device 'particularlyadapted for use in the permanent wavingo'f hair." Another object is the provision of such a curl-winding device having improved power-contr0l means for controlling the operation thereof.

In certain respects, the present invention is an improvement upon the power-driven curlwinding device shown and described inthe pending application of Virginio'l]. Gentile Ser. 'No. 675,459, filed May ll, 1933, but in other respects the invention is of more general application;

' In accordance with the presenternbodiment of the invention, means are provided for tensioning and winding a growing tress of human hair helically about'a curling rod, and preferably for covering the tress with tape as it is wound. Motor means are provided for rotatably driving the winding head about the curling rod, and preferably comprise an electricmotor coupled to the winder by means of a flexibleshaft, reduction gearing and a friction orcentrifugal clutch. In accordance with 'thepresent invention, the driving motor is controlled by means of a switch in the 'motor circuit and positioned in 'thehand gri portion of the winder'where it is always easily accessibleto the operator and 'can'be readily manipulated so asto insureperfect cone trol at all times of the winding operation.

It will be understood that the foregoing general description and thefollo'wing detailed description as'wellfare exemplary and explanatory of the invention but are not restrictive ther'eof.

Referring now'in detail to the illustrative embodiment of the invention as shown in'the'accompanying drawings, the winding means comprises a handle portion 10 in which isrotatably mounted a relatively long'tubular body 11 adapted toreceiv'e an axially movable curling rod on which the hair is'to be wound. At' the forward end of the tubular body 11 is positionedfa' comb and tensioning means 12 through which the hair passes as it 'is' Woundon the curling rod, and tape guiding means" 13 for guiding tape and wrapping it around the wound hair during the winding operation. A shaft 15 projects from the tubular loodyll andis adapted to support a roll of tape '14. Inasmuch as the details of the foregoing construction comprise no part of the present invention, they will not be further shown or described] The rear portion of the cylindrical body 11 is preferably provided with an internal gear 16 adapted to mesh with a driving pinion -17 rotatably mounted in the handle portion 10 by means of an integral shaft 18, which in turn is driven from the keyed end 19' of flexible shaft 20 detachably secured to the rear of the hand grip 10, as shown in detail in Figure 4 of the drawings. I

The weight of the winding head and flexible shaft is preferably supported by means of a cord 21 running over pulleys 22' which are rotatably mounted in the horizontal arm 23 extending laterally from the standard 24, the other end of the cord 21 being'connected to a counterweight 25 which balances the'weight of the winder and shaft and "isadapted to hold the winding head in anyvertical position.

m ithin base 26 from which rises standard 2e, islocated the driving motor 2'7 which is'a'dapted "to'itransmit power through asuitable friction clutch through the"reduction gearing 28 and therebydrive the vertical shaft 29 which is operasveiy "connected with the lower end of the flexible shaftZO'. 'The frictioniclutch limits the amount ofpower whichcanbe transmitted by the motor to the winder, and thereby pre'i'rents stalling of the motor-in case a snarled" tress of hair prevents rotation of the winder head. if-Iowe'vr, Iprefer touse a centr-ifugally operated frictron clutch so as to insure smooth and relatively starting of :the winder, 'and 'for this purpose the motor shaft 30 is provided at one end with a centrifugal clutch spider 31 received within the centrifugal clutch drum 32 and coaxial therewith, drum 32 being rigidly secured to the end of the high speed shaft 33 of reduction gearing 28. The radial vanes of clutch spider 31 drive the weighted friction blocks 34, and when the motor has attained sufficient speed, these blocks 34 are forced radially outward into engagement with the inner cylindrical surface of the drum 32, causing it to be rotated. In case the load on the winder is too great, the spider 31 and blocks 34 rotate within the drum 32, but under normal conditions they rotate with the drum until the motor is stopped thereby releasing the pressure of the blocks against the drum.

For controlling the application of power to the motor and thereby the rotation of the winder, the interior of the hand gripped portion 10 of the winder head is preferably recessed and receives the spring mounted contacts 38 which are supported on a block of insulated material 39, and are connected in series with the motor by means of conductors 40. For conveniently operating the switch during the use of the winder, a small bell crank 42 is pivotally mounted in the hand grip 10 by means of pivot pin 43 supported on brackets 44 mounted on hand grip 10, the longer portion of the bell crank projecting forwardly of the winder, and its short arm being adapted to bear against and move the insulated head 45 of spring plunger 46.

As the operator presses down on the forward end of bell crank 42, the switch contacts 38 are closed thereby causing power to be supplied to motor 27 from the conductor 50 and to conductors 40. As soon as the curl has been completely wound, or whenever the operator desires to stop the winding operation for any reason, he need only remove his-finger from the bell crank lever 42 to stop the motor, the contacts being open by virtue of their own resiliency, and lever 42 being raised to the position shown in Figure 4 by means of the spring plunger 46.
